Officials from KSW, a promotion based in Pudzianowski’s native Poland, today announced the 33-year-old returns at KSW XIII, though an opponent has not been revealed.

The booking means a potential April 23 matchup with ex-UFC champ Tim Sylvia (25-6) is now unlikely.

As MMAjunkie.com (www.mmajunkie.com) reported over the weekend, the Pudzianowski fight was one of three Sylvia and agent Monte Cox had been considering. The Korean-based fight promotion Moosin reportedly hoped to host the Pudzianowski vs. Sylvia fight at the DCU center in Worcester, Mass.

When Cox spoke to MMAjunkie.com, the fight was in advanced negotiations but not signed. (Legislation sanctioning MMA in Massachusetts goes into effect today.)

The May 7 KWA card will be held in Katowice rather than Warsaw for a larger venue (the 11,000-seat Spodek arena) that can accommodate more fans. Pudzianowski first fight, which ended in a submission victory (due to strikes) over Marcin Najman, was watched by approximately 15 percent of Poland’s 38 million residents. Polsat, the country’s second largest television station, aired the show and will broadcast the next one, as well.

Mamed Khalidov, who recently defeated Sengoku champion Jorge Santiago in a non-title fight and gets a shot at the belt on March 7 Sengoku Raiden Championships 12, is also expected to compete on the card, though his opponent also was not named.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
